INNOAIR: Innovative demand responsive green public transportation for cleaner air in urban environment

Guidebook on air pollution interdependencies for various stakeholders

The INNOAIR team is pleased to announce that the Guidebook on air pollution interdependencies for various stakeholders is now published. You can download the guidebook here.

The guidebook, prepared by the National Institute of Meteorology and Hydrology (NIMH) and Sofia Development Association, is a free tool for policy, research, education, industry and environmental bodies to understand the processes leading to undesired high levels of pollution in urban areas. The document tries, in an understandable way, to summarize what factors influence the levels of various pollutants in the atmosphere and how their adverse influence can be eliminated or limited in order to improve air quality in cities in a short- and long-term time horizon.

The guidebook starts by giving a general overview of what the meteorological conditions in urban areas can be, what the major air pollutants in the air are, the air quality standards by the European Union and World Health Organization (WHO) and how air pollution can impact the human health, ecosystems and biodiversity, climate change and cultural heritage. This general information provides the reader with the background information on the subject needed to better understand the case of Sofia. This sets up perfectly for the next section, which explains the monitoring of air pollution in Sofia.

An important part of the guidebook is the air quality management strategies and good practices, which outlines the best strategies and practices that can be seen around the globe. The guidebook finishes off with an overview of the specific interdependencies.

Best practice analysis on common global initiatives

The INNOAIR team has produced an innovative research paper and it is pleased to share it with the public. The Best practice analysis on common global initiatives is now published and can be downloaded here. The analysis evaluates on-demand transportation initiatives and “transport as a service” approach in Europe and on a global scale to provide project partners and the general public with guidance on lessons learned and help them avoid mistakes during the project implementation.

This document, prepared by the National Association of Municipalities in the Republic of Bulgaria (NAMRB), contains a review of the trends in mobility solutions, related to the main innovation of INNOAIR, namely on-demand transport (with electric minibuses) combined with “mobility as a service” like technologies, low emission zones and congestion charging model. The analysis provides guidance for tested solutions, the challenges they address, main findings and results. That way interested parties could avoid past mistakes and use the information provided for further guidance and enhancement of the INNOAIR model.

The analysis starts by giving an overview of the general trends related to the main innovation of INNOAIR and continues by providing concrete examples of already established such innovations mainly in cities in Europe and around the world. The document ends by giving the main findings and lessons learned based on the already processed information in the previous sections.

INNOAIR project is co-financed by the European Regional Development Fund through the Urban Innovative Actions Initiative. This is the first Bulgarian project selected for funding by UIA.


Multi-stakeholder dialogue on air pollution interdependencies Workshop report

Air pollution in Sofia has long been a problem and despite recent positive developments, the city is still struggling to overcome this complex challenge. Air quality measures are interrelated and finding out how they affect each other will help optimize them faster.

In this regard, on November 12, 2020, the INNOAIR team launched its multi-stakeholder dialogue on air pollution interdependencies. Nearly 100 stakeholders from universities and research institutes, community organizations, city administration, NGOs, national agencies, businesses and investors, took part in an online dialogue event and engaged in a conversation about the future. Diverse perspectives were voiced pointing to various interdependencies: the more precise and timely feedback the city provides on the effect of its policies, the stronger the citizen commitment; the less measures for support of the energy poor, the more air pollution from old cars and household burning; the less air pollution, the bigger biodiversity; the newer the urban district, the more pollution from construction and underdeveloped infrastructure, to name a few.

You may find more information about the air pollution interdependencies in Sofia, as well as conclusions and recommendations, in the full report from the online dialogue HERE.


Developing ideas for stimuli for citizens to switch to sustainable transportation - Co-creation Workshop Report

The transition to the use of public and sustainable transport is a task that requires motivation not only from institutions, but also from citizens and the business sector. In this regard, Sofia Development Association, in partnership with Sofia Municipality, organized a co-creation design workshop in the framework of INNOAIR project, which was held online on February 23, 2021. More than 30 participants, among which young and active citizens, businesses and local institutions, took part in a lively discussion to identify incentives to stimulate citizens to give up everyday car use and switch to sustainable transport in the city.

The design workshop used a variety of tools and approaches to gather ideas. The meeting was held in the form of an open discussion on an online platform, combined with a real-time collaboration tool (an online whiteboard), where participants anonymously added their ideas. During the conversation, various proposals for incentives were discussed, ranging from the creation of an application that integrates all types of transport services in one access system, to the creation of an information campaign with general publicity, from parking discounts to integrated pricing policy with municipal cultural services. institutes. All discussed proposals for future incentives, a list of existing practices for promoting the use of public and sustainable transport in Sofia, as well as recommendations and conclusions from the discussion can be found HERE.





In the first edition of the INNOAIR project newsletter, you will find not only information about the key developments in mobility in recent months, but also:

- Results and analysis of a survey on citizens' attitudes towards the transition to active transport.
- Information on the introduction of low-emission zones in the capital.
- Opportunities for involvement in the creation of solutions for innovative urban mobility.
